BACKGROUND OF THE INVENTION

Embodiments of the present invention are directed to user interfaces and more particularly to techniques for providing user interface which allow users to select filtering criteria and display filtered information accordingly.

In today's information age, an increasing amount of data is being collected and stored every second. Satellites orbiting earth record information and photograph our planet everyday, and they send the information and photographs back to earth. Millions of computers on the Internet collect all types of information, ranging from network usage to marketing data. All types of organizations, large and small, store information such as personnel data, operational costs, etc. New tools are being invented to make collecting data easier, faster, and more convenient than ever before.

Data, no matter how it is collected, is only meaningful and useful to people when logically organized and stored. For example, computers often rely on data structures to store data in predefined fields. For large amounts of data, people usually rely on databases, where structured collections of data and/or records are stored in computer systems in accordance to predefined rules and/or database models.

Relationship models, hierarchy models, and network models, are common models for use in databases representing relationships among entities of information stored in databases. Typically, a database relies on database software to organize and manage data and/or entities of information. For example, database software organizes, stores, and/or records data using various types of database models.

Graphical user interface (“GUI”) is a helpful way for displaying data and showing the relationships thereof. Numerous conventional graphical interfaces are capable of displaying information in a hierarchical view. Unfortunately, merely being able to see information in a hierarchical view is often not enough, as it may be difficult to identify which parts of the information are of interest.

Therefore, new and improved graphical user interfaces for displaying hierarchical information are desired.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention are directed to user interfaces and more particularly to techniques for providing user interface which allow users to select filtering criteria and display filtered information accordingly. In various embodiments, related information is displayed on a hierarchical chart as nodes that are connected to one another. The hierarchical chart is updated after filtering criteria are applied, and the display visibility of the nodes is changed based on the filtering results. The hierarchical relationships among the nodes are maintained before and after the filtering process. In a specific embodiment, the nodes that do not meet filtering criteria are displayed at a low visibility level on the hierarchical chart.

As explained above, conventional techniques are available for filtering information, however, the conventional filtering processes are often inadequate because the filtered information often fails to show its relationship to other types of information. For example, when a filtering process is performed, only information items that meet filtering criteria are displayed, the information items that do not meet the filtering criteria are not displayed. From a user's perspective, it is often difficult to understand the relationship between the information items that meet the filtering criteria and those that do not. It is therefore to be appreciated that embodiments of the present invention present information in the form of a hierarchical chart and display filtered information while preserving the hierarchical relationship that is displayed.

FIG. 1 is a simplified diagram illustrating data flow for processes according to embodiments of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications.

As shown in FIG. 1, a system 100 includes the following components:

1. a database 101;

2. a processor module 111;

3. a user interface module 112;

4. a rendering module 113; and

5. a display 120.

As an example, the processor module 111, the user interface module 112, and the rendering module 113 are parts of a controller module 110.

The database 101 is connected to the controller module 110. Depending on the application, the database 101 may be implemented as structure data stored on a local memory device, such as a hard disk, flash memory, etc. In one embodiment, the database 101 is stored at a network location. In one embodiment, the database 101 is an integral part of the system 100.

Among other features, the database 101 stores data that represents various entities that are related to one another. The database 101 stores relationship data representing the relationship among these entities. Each of these entities is associated with one or more attributes. In one embodiment, the attributes are categorized. For example, an entity in the database 101 represents a manager in a personnel database, and the manager has attributes that include name, address, salary, title, etc. In various embodiments, the attributes of each of the entities can be used as filtering criteria.

The processor module 111 is configured to obtain information from the database 101. For example, the processor module 111 retrieves both entities data and relationship data mentioned above and processes these data. In various embodiments, the processor module 111 determines category and/or view information and attributes for each of the entities in the database. For example, during the filtering process, the processor stores the filtering criteria and the entities that meet the filtering criteria using the status indicator 103.

Once the processor module 111 processes the information from the database 101, the processor module 111 generates a hierarchical chart that is to be displayed on the display 120. As shown in FIG. 1, processor module 111 sends the hierarchical chart to the rendering module 113 for rendering on the display 120. As shown in FIG. 1, the display 120 is used to display the hierarchical chart. For example, the hierarchical chart includes a number of nodes and links. Each of the nodes represents an entity and/or concept that is stored in the database. The links among the nodes represent the relationship among the nodes. For example, if the status indicator 103 indicates that only a few nodes meet filtering criteria, the processor module 111 uses the information from these nodes in a hierarchical chart for display at a one display setting, and the nodes that did not meet the filtering criteria at a different display setting (e.g., dimmer, blurred, reduced size, etc.)

The controller module 110 as shown includes a user interface module 112 for receiving user inputs. When user input 102 is received, the display 120 updates accordingly. For example, when user input 102 indicates what filtering criteria should be used, the user input received by the user interface module 112 and processed by the processor module 111 does what?. The processor module 111 determines which nodes meet the filtering criteria and stores these nodes in the status indicator 103, and retrieves additional information from the database if necessary. The processor module 111 then generates an updated hierarchical chart, with one or more nodes changing the display setting (e.g., increased or decreased visibility levels). The updated hierarchical chart is then rendered by the rendering module 113 and displayed at the display 120.

Depending on the operational mode, the change of view for the nodes may work in different ways. In one exemplary scenario, the view for each node on the hierarchical chart is changed and synchronized to one specific view, if a view selection is made at a global menu and all of the nodes are selected for view change. On the other hand, if a user selectes one or more nodes of the hierarchy, only the selected nodes will change the view. The detailed operation of displaying and updating the hierarchical chart is described in more detail below.

FIG. 2 is a simplified diagram illustrating a graphical user interface according to an embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications.

A graphical user interface 200 is shown in FIG. 2A. The graphical user interface 200 contains a display region 208 and a menu region 206. The display region 208 displays a hierarchical chart 210. The menu region 206 typically comprises various user-selectable controls for performing various operations (not shown in FIG. 2) such as opening a file, copy and paste operations, etc. The operations may change depending on the specific application for which the graphical user interface is displayed.

The display region 208 is used for displaying hierarchical information. For example, as depicted in FIG. 2, display region 208 displays a hierarchical chart 210 comprising a plurality of nodes 211-215 and links 220-224 connecting the nodes. Each node represents a concept or entity involved in the hierarchy depicted by hierarchical chart 210. The links between the nodes represent hierarchical relationships between the concepts or entities represented by the nodes. For example, if hierarchical chart 210 represents an organization personnel hierarchy, the nodes of hierarchical chart 210 may represent persons involved in the hierarchy and the links may represent hierarchical relationships between the personnel. For example, node 212 may represent a director, nodes 211, 213, and 214 may represent managers under the director, and node 215 may represent an employee under the manager represented by node 211. Each node may display information related to the entity or concept represented by the node. For example, the nodes in FIG. 2 may display names (e.g., Name 1, Name 2, etc.) corresponding to the people represented by the nodes. It is to be understood that other information items may be displayed as well.

According to embodiments, nodes 211-215 in FIG. 2 correspond to records stored in a database. The records in the database relate to one another, and the relationship is stored in the database as relationship data. For example, the links 220-224 correspond to visualization on the graphical user interface 200 of the relationship data. To provide a more specific example, node 212 corresponds to a record of a director and nodes 211-214 correspond to records of managers under the director, and the records for both director and managers stored in the data contain the hierarchical relationship information. In addition to relationship data, the database also contains various attributes associated with each record. In one embodiment, each of the records stored in the data contains various fields for storing various attributes. Going back to the example above, the record that stores information for the director may contain attributes such as name, address, contact information, salary, availability, performance, etc. Similarly, the records for managers may contain information such as name, address, contact information, salary, availability, performance, hours worked, vacation time, etc.

In one embodiment, the graphical user interface 200 has a default setting for displaying all of nodes 211-215. For example, nodes 211-215 represent all of the nodes that are in the chart 210. Depending on the filtering criteria selected by the user, one or more of these nodes changes its visibility.

As shown in FIG. 2, the menu region 206 includes a filter menu 202. The filter menu 202 provides a number of filter criteria. For example, as shown in FIG. 2, the filter criteria 1-5 are based on the attributes associated with the nodes. In a specific embodiment, the filter criteria 1-5 are predefined. For example, when displaying a hierarchical chart that contains nodes associated with personnel data, filter criteria would include performance, full-time employees, etc. Similarly, in an exemplary hierarchical chart that contains nodes associated with production line information, filter criteria would include machine type, throughout threshold, etc. In one embodiment, filter criteria shown in the filter menu 202 are automatically determined by a computer program. For example, the computer program processes each of the records to determine their attributes and automatically generates the filter criteria based on the records and/or attributes.

According to various embodiments, filtering criteria may be user defined, as explained below. FIG. 3 is a screen shot of an exemplary graphical user interface according to an embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In FIG. 3, the graphical user interface 300, on which a hierarchical chart 306 is displayed, includes a filter menu 302. Filter menu 302 includes a predefined menu selection 302A that is labeled “High Performance Employees.” The filter menu 302 also includes a user filter selection 302B that allows users to set filtering criteria. As shown, the user filter selection 302B is labeled “Show Filter Criteria.” When a user selects filter selection 302B, a window 304 appears, which allows users to manually input various filter criteria values, such as “Department,” “Job function,” “Length of Service,” etc. Depending on the type of value, a user may select value from a drop down menu (e.g., “Department”) or enter numerical (e.g., “Length of Service”) and/or alphabetical values. As shown in FIG. 3, a user may enter more than one criterion in the window 304 to narrow down the filtering process.

Once the filtering criteria are defined, the program performs the filtering process to determine which nodes on the hierarchical chart meet the filtering criteria and which do not. Depending on the specific implementation, various types of filtering algorithms may be used. In an embodiment, a filtering algorithm according to the present invention retrieves and processes information associated with each of the nodes. For example, the filtering algorithm determines, one by one, whether a node meets the filtering criteria set by the user. After the filtering algorithm is completed, it generates a set of data indicating which nodes satisfy the filtering criteria and which do not.

It is to appreciated that embodiments of the present invention provide a user friendly graphical user interface. In various embodiments, the hierarchical relationships among the nodes are maintained while illustrating filtering results on the graphical user interface. FIG. 4 is a simplified diagram illustrating a filtered display of a hierarchical chart according to an embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications.

As shown in FIG. 4, a graphical user interface 400 includes a display region 408 and a menu region 406. The display region 408 displays a hierarchical chart 410. The hierarchical chart 410 includes nodes 412-415. As explained above, each node represents a concept or entity involved in the hierarchy depicted by hierarchical chart 410. For example, each node is a representation of a record stored in a database. The links between the nodes represent hierarchical relationships between the concepts or entities represented by the nodes. For example, if hierarchical chart 410 represents an organization personnel hierarchy, the nodes of hierarchical chart 410 may represent persons involved in the hierarchy and the links may represent hierarchical relationships between the personnel.

The menu region 406 includes a filter menu 402. A user is able to use the filter menu 402 to select one or more filtering criteria. For example, the user selects “Criteria 1” (e.g., user selection indicated by the underline) in the filter menu 402. To provide an example, node 413 does not meet “Criteria 1” and is thus filtered out. Under conventional filtering schemes, node 413 would disappear from the GUI. In contrast, node 413, which is filtered out, is still displayed at the GUI and the hierarchical relationship of the hierarchical chart 410 remains unchanged. Depending on the application, there may be other ways to illustrate the filtering of nodes. In FIG. 4, node 413 that does not meet the filtering criteria is displayed as a shaded node, which makes node 413 less visible than the other nodes on the hierarchical chart. But it is to be understood that node 413 may be displayed at a low visibility level (compared to nodes that meet filtering criteria) in other ways, such as reduced size, blurred image, dimmed, etc. The links among the nodes are maintained, even for node 413. It is to be appreciated that by maintaining the links, the hierarchical relationship among the nodes is maintained and visible.

FIG. 5 is an exemplary screen shot of a hierarchical display where filter results are displayed according to embodiments of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In the screen shot 500, the hierarchical chart 510 shows that node 504 that does not fit filtering criteria being dimmed. The nodes that meet the filtering criteria, such as node 502, remain visible.

In a specific embodiment, the node that meets the filtering criteria is displayed at an enlarged size. FIG. 6 is a simplified diagram illustrating the display of a filtered hierarchy according to an embodiment of the invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIG. 6, “Criteria 3” is selected at the filter menu 602. For example, also in the menu region 606 is the filtering mode menu 604. In FIG. 6, node 614 is displayed within display region 608. For example, node 614 is displayed at a larger size compared to node 612, as node 614 meets the filtering criteria while node 612 does not. A photo 616 is displayed on node 614, as the large display size of node 614 affords area for photo display. It is to be appreciated, as shown in FIG. 6, that node 614 is still connected to node 612 through a link, and that hierarchical relationship among nodes is preserved and displayed.

FIG. 7 is a simplified diagram illustrating a system for implementing various embodiments of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications.

FIG. 9 is a simplified flow diagram illustrating a process of displaying a hierarchical chart with filter nodes according to embodiments of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. For example, various steps as shown in process 900 may be added, removed, replaced, rearranged, repeated, modified, and/or overlapped.

At step 901, node information is retrieved. For example, the node information includes information regarding entities represented by the nodes and relationship data thereof. At step 902, a hierarchical chart is displayed. On the hierarchical chart, nodes are displayed and the relationship among the nodes is displayed as links connecting the nodes.

At step 903, filtering criteria are received and processed. For example, the filtering criteria is provided by the user. Based on the filtering criteria, it can be determined which nodes meet the filtering criteria and which do not, at step 904. At step 905, the hierarchical chart is updated based on the results from filtering. At step 906, the nodes that do not meet the filtering criteria are displayed at a different visibility level (e.g., blurred, shaded, resized, etc.) compared to nodes that meet the filtering criteria. According to various embodiments, all of the nodes and their links are displayed before and after the filtering. For example, the hierarchical chart that has a filtered node still retains its hierarchy, as the nodes that did not meet the filtering criteria remain displayed on the hierarchical chart, only at a different visibility level.

Although specific embodiments of the present invention have been described, various modifications, alterations, alternative constructions, and equivalents are within the scope of the invention.
